rails 4，表单中的ajax更改方法

Question

我可以在第一次点击时点赞并更新点赞数，但在第二次点击时就不行了。我在帖子需要更改的地方对其进行了调试，但我无法弄清楚如何更改 ajax 调用中的表单方法。

skit_controller.rb

def like
  @skit.liked_by current_user   if request.post?
  @skit.unliked_by current_user if request.delete?
  respond_to do |format|
    format.html { redirect_to skits_path, notice: 'Successfully voted!' }
    format.js
  end
end

routes.rb

resources :skits do
  resources :challenges
  match :like, via: [:post, :delete], on: :member
end

index.html.haml

- @skits.each do |skit|
  = render skit

_skit.html.haml

.votes
  - method = current_user.liked?(skit) ? :delete : :post
  = link_to like_skit_path(skit), method: method, remote: true, id: "post-#{skit.id}" do
    .upvote
      %span.upvote-link
        %i.fa.fa-caret-up
      .vote-count= skit.votes_for.size

like.js.erb

$("#post-<%= @skit.id %>").find(".vote-count").html('<%=j @skit.votes_for.size.to_s %>');

我认为每次有人单击按钮时我都需要更新方法，因此用户可以:post 点赞或:delete 点赞，但它只是停留在 POST 方法。

我们将不得不更新您的布局。

skits/_skit.html.haml

.skit-wrapper{id: "skit-#{skit.id}"}
  =render partial: 'skits/skit_wrapper', locals: {skit: skit}

skits/_skit_wrapper.html.haml

.votes
  - method = current_user.liked?(skit) ? :delete : :post
  = link_to like_skit_path(skit), method: method, remote: true do
    .upvote
      %span.upvote-link
        %i.fa.fa-caret-up
      .vote-count= skit.votes_for.size

like.js.erb

$("#skit-<%= @skit.id %>").html("<%= escape_javascript(render partial: 'skits/skit_wrapper', locals: {skit: @skit}) %>")
